3VJ10 MCCB, Thermal Magnetic Trip Unit - 3VJ1002-3DB32-0AA0

Product Description

Siemens 3VJ10 MCCB – Thermal Magnetic Trip Unit – 3VJ1002-3DB32-0AA0

The Siemens 3VJ1002-3DB32-0AA0 is a SENTRON 3VJ10 series molded case circuit breaker (MCCB) designed for reliable protection of low-voltage electrical distribution systems against overload and short-circuit faults. It is commonly used in industrial, commercial, and OEM panel applications where compact, cost-effective, and dependable circuit protection is required.

This MCCB belongs to the 3VJ10 frame size (up to 125 A class) and uses a thermal magnetic trip unit (ATFM – Adjustable Thermal, Fixed Magnetic), which provides adjustable overload protection and fixed instantaneous short-circuit protection for stable and predictable tripping behavior.

With a rated current of 20 A and a breaking capacity of up to 25 kA at 415 V AC, it offers strong fault interruption capability suitable for industrial distribution networks and machinery protection systems.
